Electrical Coincidence Factor Calculator
Use Electrical Coincidence Factor Calculator when the question is to calculate coincidence factor from coincident demand and sum of individual peaks and the inputs come from one consistent source case.
Calculate Coincidence factor
Keep Electrical Coincidence Factor units and measurement conditions consistent before comparing coincidence factor.
Set up Electrical Coincidence Factor carefully
The setup starts with Coincident demand, and Sum of individual peaks. Keep those entries on one unit basis before the formula is evaluated.
- Coincident demand: 180 kW in the sample case.
- Sum of individual peaks: 250 kW in the sample case.
If this answer becomes an input to Electrical Diversity Factor, copy the value with its units and source note attached.
What coincidence factor means here
Electrical Coincidence Factor is most useful when the task is to calculate coincidence factor from coincident demand and sum of individual peaks. It keeps the arithmetic visible and separates that case from nearby electrical questions.
Electrical Coincidence Factor is only useful when demand interval, tariff period, and metering basis match.
Using the Electrical Coincidence Factor answer
If coincidence factor is near a limit, preserve the calculated value from Electrical Coincidence Factor and apply required margin after the calculation.
Testing coincident demand
Using the sample values, Coincident demand = 180 kW; Sum of individual peaks = 250 kW, the primary result is 72.00%.
This Electrical Coincidence Factor one-input test is a scale check, showing direction and sensitivity without turning the changed case into a recommendation.
If the changed sum of individual peaks comes from a real measurement, keep the original Electrical Coincidence Factor run so the source of the difference remains clear.
When the scope changes, move to Electrical Load Factor and leave this run as the original reference.
Checks outside Electrical Coincidence Factor
Loads must belong to the same aggregation.
- Seasonal billing rules
- Taxes and fees
- Tiered rates
A numerically valid Electrical Coincidence Factor result can still be wrong if the field condition, connection type, tariff period, or equipment rating does not match.
Before saving coincidence factor
Why might a real measurement disagree?
A field reading for Electrical Coincidence Factor can include losses, tolerance, temperature effects, waveform distortion, or instrument limits that the worksheet does not model.
